CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typ values are for information purposes only. Unless otherwise noted, all tests are
at the specified temperature and are pulsed tests, therefore: T J = T C = T A
Electrical Specifications
V DD = V IN = V EN = 3.3V, C 1 = C 2 = 10μF, L = 1.8μH, V O = 1.8V, unless otherwise specified.
